Updated ·Vorp Labs
The model puts major crime in Plymouth at 73% below the U.S. rate per resident: 90% lower for persons crimes and 69% lower for property crimes. Expected major crimes are down 8.7% from a year earlier.
- Modeled from FBI crime data for the police agencies serving Plymouth. Where an agency didn't report to the FBI, its totals are estimated from its past reports or similar agencies.
- The model estimates about 4.7 major crimes per 1,000 residents a year (0.3 violent, 4.4 property), against 17.2 for the U.S.
- By the model's major-crime rate per resident, Plymouth is lower than 75% of the 104 other Connecticut places and 88% of the 8,446 other places nationwide on CrimeMetric.
Where these numbers come from
The estimates start from what police agencies report to the FBI, modeled across Plymouth's 11 census block groups for 11,973 residents. How Connecticut residents' crime totals reach the FBI: detailed incident reports for 86.3% and no reporting agency of their own for 13.7% (shares of 2020 residents). Sources · Method
- Year: many show an agency's last full FBI year (often two years back). These figures are the model's estimate for the current year, release 2026-11-10.
- Crimes counted: some add simple assault, vandalism or drug offenses to "violent" or "property" crime; here major crime is persons plus property crime, and social disorder is separate.
- Area: an agency's totals cover its jurisdiction, which can differ from the city's limits; these are summed over the block groups inside Plymouth.
- Scale: a grade or a 1-to-100 score ranks places against each other; a rate per 1,000 residents and an index against the U.S. rate don't.
Rates are the model's estimates of reported crime per 1,000 residents a year. Index: 100 is the U.S. rate per resident; 200 is twice it. How we calculated this

How we calculated this
Each police agency's crimes, as reported to the FBI or estimated where it didn't report, are spread across the census block groups it serves using population, jobs, points of interest and, where available, local incident records. Plymouth's figures add up its 11 block groups. The index compares crimes per resident with the U.S. rate.
- Plymouth has no published incident records in our data, so its estimate relies on agency totals and neighborhood characteristics.
- Rates are per resident, so places where many people work or visit but few live, such as downtowns, airports and stadiums, can read high.
- Disorderly conduct and trespassing are modeled, because the FBI records them only through arrests.
- Residents: 11,973. Model updated Nov 10, 2026. Release 2026-11-10
